Application filed November 14, 1913. Serial No. 801,013.

To all LU/tom t may concern:

Be it known that we, Moses SHERMAN and BERT RIVKIN, citizens of thevUnited States,

and residents of New York, in the county of New York and State of NewYork, have The object of the invention is to provide a simple andinexpensive means for locking a vehicle to prevent the theft thereof.

The further object is to provide a brake of this kind which will preventone or more of the wheels from revolving and cause them to drag upon theroad bed. and thus prevent the vehicle from being easily and quicklytransferred from one locality to another, and if a theft is beingperpetrated the culprit can be easily overtaken and located by thetracks made by the dragging wheels, and the locked wheel of the vehiclewill also indicate, if the vehicle is in motion, that a theft is beingcommitted.

The still further object is to provide a brake of this character whichcannot be released by any one except he is provided with the properlkey, and to prevent dishonest drivers after leaving the employment of afirm from using a duplicate key which they may have made while in chargeof the ve-v hicle.

l/Vith these and other objects in view, it will be seen that weaccomplish the foregoing, by referring to the accompanying drawingsforming a part of this specification and showing one of the principalembodiments of our invention and while we have shown this one principle,we wish it understood that many changes may be made in the various partsand arrangement thereof without departing from the spirit and scope ofo-ur invention, and we wish to reserve these rights.

Referring to the accompanying drawings," Figure 1 is a side elevation ofone style of delivery wagon partly in section or broken away to moreclearly show our invention and how it is applied; Fig. 2 is a plan ofour invention as shown in Fig. 1, a portion of the wagon being shown orindicated by dotted lines; Fig. 3 is a top plan of the lock and showinga portion of the locking niember; Fig. 4 is a plan of the lock with theupper portion of the casing removed; Fig. 5 is ,a side elevation, partlybroken away and showing almost a true central vertical section; Fig. 6is a view similar to Fig. 3, but showing the spring plate thrown openand the lock ready for the insertion of the key; Fig. 7 is a bottomplanV of the upper portion of the lock casing and showing the retainingmeans of the spring plate; Fig. 8 is a vertical section taken on theline v1--1 of Fig. 3, looking in the direction of the arrow a; Fig. 9 isa top plan of a retaining plate which carries the locking members andkey stud and obstruction pins; Fig. 10 is a side elevation of theretaining plate and locking members, and Fig. 11 is a side elevation ofthe key.

Referring to Figs. 1 and 2, it will be seen that we provide a brakemechanism for a standard make of wagon. The mechanism isoperated by thefoot of the driver, but can only be released by a key, and consists of afoot lever 2, which is pivoted to a bracket 3 secured to the wagon. rlhelever 2 is provided with a pivoted link 4, which is connected to thelink 5 supported by a bracket 6 secured to the wagon. The lever 5 isprovided with a slot 7 in which operates a pin 8 of the operating rod 9,which passes through holes in the cross members of the wagon, whichserve as bearings for the rod, or other suitable bearings may beprovided. The rod 9 is provided with two transverse members 10, whichare held in position by lock nuts 11 with which to adjust the members 10relatively to the foot lever mechanism and the locking mechanism. rllhemembers l() are pinned to or otherwise secured to the main operating rod12, which is provided at its rear end with a Yeshaped fork 13, to whichare connected two pivoted links 14, and the links are in turn connectedto two locking rods 15 and held in position Vby suitablebearings 16,which are bolted to `blocks 17 secured to the wagon.

sitionbyfthe springs 18 connected Vto the crossmember 19, V(secured tothe main operating rod 12), and the eye-bolts 20 secured pass throughand the front plate or side 25 forming a bearing' for the rod.

Referring to Figs. 3 to .8, it `will be seen thatthe lock 24 Consists oftwo casings 26 Y Y retaining screws 29,'-which are `screwed into and 27.

rThe bottom'casingV is provided witha bottom plate28, through which passthe upper casing and pass through the reinforcing plates Y yand the topplate 31 of the lock and arejriveted or headed over, thus preventing thelock" from being taken apart except by a machinist; The upper casing 26is held in alineinent with the lower casing by the pins 32 of the uppercasing vbeing-inserted into the holes 33 ofV the' lower casing. Thelower casing has at its frontend a portion of its top plate 34 y `bentvdown, forming a partial wall or parti- Y two compartments 36 and 37.

throughthe compartment 37 and secured in Y.

tion and dividing the lower casing into Passing the'partitionv35 and therear wall 38 is a .Cylindricaltube 39, through which pass the lockingmembers21 to be engaged by the depending arms 40 of the pivoted arms 41,

:which are carried on'a pivot stud 42 secured in the retainingrplate43.` VThe arms 41 are held in locked position by the springs 44 securedto the plate 34 by the retaining blocks 45 and give additional pressureor retaining force to lthe arms 41 by abutting the pins 46." VTheretaining plate'43 is secured to the plate 34 by screws 47, and car-Vries the key stud 48 and obstruction pinsY Upon the top plate 50 areriveted two kplates 5 1 and 52, in which is located a shaft 5 3, upon.which swings a springrplate 54, (which covers the key hole and isprovided with a Vpair of springs 56'to throw the plate open when thecatch 57,y which passes through the opening 58, is released by the latch59, held invpositiron by the lspring 60 and operated by the slidingmember 6l, which'is guided by the reinforcing plate30 and operated by aconnecting member 62 passing through a slot 63V in the K plate 50 andconnecting it' to the sliding I co member 64.*V Y.

The operation is very simple. When theY driver stopshiswagonrhe Ysimplyputs his Vfoot upon the lever2 and it is 'pushed` for- Y ward.Thisvcauses,through the link 4, the

' levervr5 to swing 'onits pivot, drawing the' Vrod 9 forward ,and alsocausing the rod 12 Y K Y to' move inthe same direction and putting astrain on the springs 18, and at the same time the rear ends of thelinks 14 are brought forward and almost into line with the rods 15. Thismovement causes the rods 15 to move in a transverse direction to the rod12 and in opposite direction of each other, and to have their ends passbetween the spokes of the rear wheels of the wagon and prevent therevolving of the same. When the rod 12 moves forward the conical end 22of the locking member 21 forces the arms 40 apart and the locking memberpasses into the locking chamber 36 and the arms 40 snap behind the face23 and hold everything in its locked position. In order to releasetherods 15 and allow them to be withdrawn, it is only necessary to push themember 64 in the proper direction, (shown yin Fig. 6), and the springplate 54 will' be thrown open, then insert the key 66 into the lock andgive it a quarter of a turn and the blades 65 of the key will force thearms V41 apart and this will cause the arms 40 to move from behind theface 23 of the locking member 22 and allow the springs 18 to return allthe other parts to their normal positions.

If it is desired at any time to change the combination of the lock forany reason, it can be easily done by simply removing the top casing andthen removing the retaining plate 43 by removing the screws 47 andsubstituting the plate 70 shown in Figs. 9 and 10, which carries armsY1-similar to the arms 41. The arms 71 are cut away at 72 and thenotches thus formed make it necessary to have a key with longer bladesin order to open the arms 71 sufficiently to release the locking member22. A further means Vfor changing the combination is the difference ofarranging the obstruction t pins 74.

lVe claim as our invention:

V1. The combination with a vehicle, of a brake mechanism comprising apair of plungers mounted to slide endwise and engage two of the wheelsto lock against movement, a lock rod mounted to reciprocate, a pair oflinks connecting said plungers respectively with said rod and arrangedto act as a toggle joint device, springs connected with the lock rod toretract it and the plungers when advanced,
